What do all the colors mean in the code?

Syntax highlighting is commonly used when displaying code to make it more readable.

I’ve taken it one step further to make things easier for you to learn!

• Green highlighted lines means it’s important! The deeper the green, the more useful the code. Skim the code without any highlights, that’s just boilerplate code.
• Blue colored text are Salesforce reserved variables or sObjects. They have useful functionality that I will teach you to master!
• Purple colored text are variables that we define. We can name them anything we want!
• // Comments begin with a doubleslash, and they’re frequently used in code to help explain what you’re doing. Salesforce will ignore these lines when executing Apex.
• ‘Strings’, also known as “text”, are wrapped in single quotes. Strings need to be differentiated from numbers, for example, because ‘3’ + ‘3’ = ’33’ and 3 + 3 = 6.
